3DCS Modeling Services

• Variation Simulation Modeling: Three-dimensional tolerance analysis aids in developing robust designs that minimize dimensional variation. When used for defining and managing products functional tolerancing and coordinating their measurement data, 3D tolerance analysis significantly reduces the rework required for engineering drawings, tools and gages.

• Current production troubleshooting: Identifying specific contributors, either from the product or the process, and rank critical components tolerances contribution & impact on the total cumulative variation, enhancing product quality while lowering costs.

Tolerance Stack-Up Analysis Training

Course Description

Tolerance stack analysis studies the mutual relationship between the allowed deviation limits between parts and assemblies. Stack computation improves understanding of the design solution, allows early identification of problems starting while still in the design stage, forms the basis for decision making and is used to optimize tolerances to reduce costs and enhance product performance.

This course provides the theoretical knowledge and practical know-how to perform stack computation and includes heavy practical exercises of generic problems, exercises, and full solutions of real problems (the possibility of applying exercises to parts and assemblies of your company is contingent on previous submission of drawings and assemblies). This is an advanced GD&T course.

Course Content

• Introduction and tolerance-stack computation definitions
• Principles and rules of stack computation
• Tolerance diagram
• Tolerance stack – casting and concentricity (part, assembly)
• Tolerance stack – profile (part, assembly)
• Tolerance stack – position
• Tolerance stack – position with material conditions – bonus and shift (part, assembly)
• Tolerance stack – form (Feature, FOS, Feature-of-Size)
• Tolerance stack – orientation (Feature, FOS)
• Integrated tolerance stack computation (part, assembly)
• Application of tolerance stack computation to tolerance optimization
• Summary practical exercise

Quality Process Consulting

Understanding and Automating Your Quality Processes

Quality is important. Getting real results and improvement from your quality processes is not easy, though. Collecting data and measurements is only the first step, as making actionable decisions from that data can take many hours of diving through large datasets, looking at huge spreadsheets and crunching statistics. 

• Quality Consultations are done by certified Six Sigma Black Belts
• Final report includes process improvements, quality system suggestions and automation techniques
• Get a basic assessment free! Decide afterwards to use DCS or utilize your own internal quality people.

GD&T Training

Why Adopt GD&T at Your Company?

There are a number of reasons to adopt GD&T at your company:

Clarity and consistency in the design process. GD&T provides a clear and concise method for defining a reference coordinate system on a component or assembly that can be used throughout manufacturing and inspection. This reduces misinterpretations and the need for costly engineering changes and rework that can result from a lack of clarity.

Dramatic time savings. By using GD&T, engineers dramatically reduce their need for drawing notes to describe complex geometry requirements on components and assemblies.

Fit with accepted design-for-manufacturing methods. The proper application of GD&T closely dovetails accepted and logical mechanical design processes and design-for-manufacturing considerations. For example, the allowable variations as defined through GD&T can be directly read, or “imported,” into 3-D tolerance analysis software such as 3DCS.

DCS offers starter and advanced courses in GD&T to get your team up-to-speed and applying GD&T concepts. 

• Basic GD&T (8 Hours)
• Advanced GD&T (24 Hours)
